Re: Mist Amiga Display

The (or one) problem with modern TVs is that they need to do some heavy processing on those ancient video signals to scale them nicely. Thus they to different extent reply on the video signal to be close to what the video standards describe which e.g. is an interlaced signal. Always! Since a valid l...

Re: USB Controllers - Why do so many not work? can we help

I shouldn't make a difference which port you use and how man other devices are connected. But it doesn't hurt to check if e.g. unplugging any of the other devices solves your problem. It seems you _have_ some problem and we need to figure out where it originates from. And i haven't tested the firmwa...

Re: USB missing power when using DC jack?

There should be no difference. Actually the main MIST board i use for development is equipped with a DC jack _and_ uses a rapoo keyboard.

I also don't think the USB chip is damaged or the like. It would then not work at all anymore. I'd also expect the power source to be the problem.

Re: Sega megadrive/genesis core

With the initial port of the fpgagen to the MIST there's now definitely the need for a decent sound implementation for it. This looks like the perfect moment to get a lot of happy users for such a chip as everything even if only partly correct is better than the current silence and will thus make ma...

Re: Sending keyboard input to MIST with an Arduino Micro

Parsing all the complex possible keyboard types that exist in the USB world is difficult. Fortunately all keyboards support a so called boot mode. The MIST makes use of this boot mode which real PCs don't as they have the horse power to parse all those complex stuff a USB keyboard reports. Does your...

Re: Philosophical question for core developpers

Re: Mattel Aquarius - how easy to port this core?

I just had a look at the archive from that other thread. It shouldn't be too hard to port this to the mist. One would have to replace the TSK80 CPU (which is a closed source z80 cpu core from altium) with e.g. the t80 core. The MISTs FPGAs internal RAM is sufficient for the whole machine, so no exte...

It might be possible to add something to one of the USB ports. The MISTs USB is quite slow, but it may be sufficient for this kind of application.

Re: Mist and an audio input... is it possible?

What i did with the first releases of the spectrum code was to actually playback a sound file inside the FPGA. This of course doesn't help with physical tapes. But it allows to play back audio data from something like the csw files which are basically just the raw data stream which you'd also expect...

Re: C16 and Plus 4 on the Mist

It should be fairly easy for you to find the colour codes inside the source code of your preferred emulator and compare that to the values in the verilog source code i previously pointed to. If you can agree on some emulators colour scheme i can replace the values in the verilog source to exactly ma...

CVBS video is imho prone to colour shifts and that's what the machines used back in the days, especially with NTSC. But i'll take a look at the values used by emulators. What emulator did you do the screenshot with? Edit: Wikipedia also has something about the plus4/c16 colour map: https://en.wikipe...
